These special mechanical, flat-tappet lifters have an oil hole in the bottom of the lifter for a constant flow of cool, pressurized oil to the cam and lifter contact point. The positive supply of pressurized oil to the most highly-stressed area of the engine further insures longer cam/lifter life, even with higher valve spring pressures. This new design, when used in conjunction with our Extreme Pressure Lubricant, brings superior lubrication to the lower camshaft/lifter interface area. These lifters work in all big block and small block engine applications, including magnums. The lifters also oil up through the pushrod, if required.These are very popular with the oval track guys or anyone who demands the ultimate in lifter technology.
These weigh approximately 101 grams each dry

This price is per lifter. A normal V8 engine will require that you order 16.
